[QUOTE=vinhen2;925848]I can't vouch for its accuracy, but the following is an older discussion in an article for the North America 84th Regiment Association. I think it mentions the highland coat you have pictured, that is in the Zeughaus Museum in Berlin (you might want to turn the sound down on your computer):

Yes, that's the same oat. You'll see that it mentions that it was lost during the war.

The original picture is interesting. I presume it's pre-war and from the museum display and shows that the staff didn't unstand how to put on the bleted plaid.

I know that the collection had some other jackets including a Napoleonic Guards' (Coldstream I think) that was discovered in a barn somewhere in Germany in 1945 by an Guards officer that recognised the buttons. This suggests that the collection was either dispersed for safe keeping an/or looted so goodness knows if the highland outfit survived.
